Title: Two-cycle engine with exhaust gas suction turbine
Inventor: YANAGIHARA SHIGERU
IPC: F02B75/02
Filed: 1981-03-03
Abstract: PURPOSE:To improve the scanvenging efficiency and increase the power of an engine by arranging in exhaustion system a turbine driven by the high speed gaseous flow at the initial period of exhaustion and sucking up the exhaust gas by the pumping operation of the turbine at the terminal period of exhaustion. CONSTITUTION:A gas exhausted from an exhaust port 3 in the exhaust stroke of a two-cycle engine is introduced into the turbine 9 within an exhaust passage 6 as a high-speed jet to rotate a moving blade 14 supported by bearings 17 and 18 between stator blades 13 and 15. In the terminal period of exhaustion where the moving blade 14 is rotated, the pressure at the turbine inlet lowers, as a result of which the pressure within the combustion chamber is decreased through the exhaust port 3. Therefore, particularly in the high-speed rotation zone, it is possible to increase the quantity of the sucked air into the combustion chamber and also to expect the improvement in the scanvenging efficiency and the power increase.

Title: Original reader
Inventor: KAWABATA TOMIKO
IPC: G03B27/50
Filed: 1995-02-17
Abstract: PURPOSE: To shorter a stop time by applying low resonance control to suppress residual vibration through resonance to a read unit when the read unit is moved from a prescribed position to a standby position and then comes to a stop. CONSTITUTION: In the mode where a read unit 1 is moved to read an image of an original 17 on an original support glass 16, the unit 1 is in standby at a prescribed position being this side of a read start position, that is, at a home position. In the low resonance control to suppress residual vibration through resonance, the rate of change in an acceleration exciting the resonance is controlled to be minimized and a square integration of a differentiation value of the acceleration is used as an evaluation function and a problem of minimizing the function is solved. Thus, approximated parts are divided depending on each position and an approximation equation of teach part is worked out.  Since the low resonance control to suppress the residual vibration due to resonance is applied to the read unit 1 in this way, when the read unit 1 is stopped to the prescribed position, the residual vibration due to resonance is suppressed thereby shortening the time required for movement to the prescribed position and for stopping.

Filed: 1988-02-12
Abstract: PURPOSE:To greatly enhance the recovery rate of valuable metals with simple operations by blowing CaCO3 powder of a specific grain sizes by a carrier gas into an electric furnace during the course of a reduction period at the time of refining a chromium steel in said furnace. CONSTITUTION:FeSi and CaO are placed on top of a molten steel upon ending of the oxidation period and the reduction period is started in the refining process of the chromium steel (about 2-35% content of Cr) in the electric furnace. The CaCO3 powder of <=0.5mm max. grain size is then blown together with the carrier gas into the slag after lapse of the prescribed time. The blowing pressure of the carrier gas is kept at about 2-5kg/cm<2> and the rate of blowing of the CaCO3 at about >=2kg/T and <=10kg/T per ton of the molten steel. Gase ous CO2 is thereby generated by decomposition of the CaCO3 powder at this time, by which the slag is foamed to reduce the chromium oxide in the slag down to metal chromium and to migrate the same into the molten steel.
